By rotary connector threaded connection on the horizontal element of straight part connection composition, the first supporting element and the second supporting element, described the
One supporting element and the second supporting element are equipped with the screw thread of opposite direction, described, and the vertical member of the first supporting element is equipped with level
Tapped through hole, the horizontal screw thread through-hole one word cutter head of interior connection rotation, the other end of a word cutter head connect rotational fastener cap,
The one word cutter head is located at the inside of the first supporting element vertical member, and the vertical member of second supporting element is equipped with horizontal spiral shell
Line through-hole, the horizontal screw thread through-hole connect hollow thread cylinder, one end turn Fastener of hollow thread cylinder, turn Fastener
The other end connect hexagonal spanner, hollow thread cylinder be equipped with handle.
The top of the rotational fastener cap is equipped with rotation movable handle.
The turn Fastener, hollow thread cylinder and hexagonal spanner constitute relative rotary motion component.
The one word cutter head and rotational fastener cap and fixator pins constitute rotary part, and fixator pins are mounted on rotation
The front end of fastening cap.
The beneficial effects of the utility model are: the I-shaped moulding of this tool, effective to improve work task efficiency, reduce
The labor intensity of worker saves the operating time and reduces bolt failure, while the tool operation is simple, and processing is transformed also very just
Benefit, equipped with one word cutter head of rotation on the vertical member of the first supporting element, in use, one word cutter head can be fastened to connection with turncap
On axis device elastic cylindrical pin bolt word deduction, rotation is carried out with swingle on the second supporting element and withstands shaft coupling elastic cylindrical pin spiral shell
Bar is fixed, and hexagonal spanner easy to disassemble is housed on hollow thread cylinder, carries out disassembly nut, on the first supporting element and the second supporting element
One plus thread and a left-hand thread, intermediate rotary connector internal screw thread run through, and are carried out by rotary connector positive and negative into button
It is supported to reach elongation and the fixed of shortening, then rotational handle dismounting couplers elastic cylindrical pin.
